IMPROVEMENT IN SCOURING BRUSH-WHEELS.

Specification forming part of Letters Patent No. 223,016, dated December30, 1879 application filed October 15, 1879.

To all whom 'it may concern:

Be it known that I, JonN A. SPENGE, of Newark, in the county of Essex,State of New Jersey, have invented a new and useful lmproveinentinScourin g BrushVheels, of which the following is a specification.

My invention consists in novel means for actuating two scouringbrush-wheels, whereby the process of scouring articles can be conductedwith great celerity and accuracy by one person, having both hands freeto manipulate his work, and whereby there will be little or no waste ofthe scouring material used, as will be hereinafter explained. l

The figure is a side elevation of my polishin g-wheels.

A A are the wheels; B B, the spindles,

.shown arranged to revolve in opposite directions, as indicated by thearrows upon the driving-pulleys O O, and iitted to slide endwise intheir journals D D, which are secured together by a tie-bar, D', andmounted upon legs E E, to support them at a convenient height.

To regulate the pressure exerted by the wheels upon the articles placedbetween them, I employ bent levers a a, provided with forked ends c', toembrace grooves b, formed in the rear ends of the spindles B, the leversbeing pivoted to the frame or tiebar at o and operated by links d,connecting them to a treadle, c.

A spring, f, attached to both of the links d, draws them upward andkeeps the wheels separated until the footis applied to the treadle.

The operation ofthe wheels will be the same if mounted vertically, thetreadle being arranged to operate upon the bottom end of the lowerspindle, to force the lower wheel against the upper when desired.

When the wheels A are set in motion bythe application of suitable power,any article of wood, metal, bone, or other substance may be insertedbetween the two wheels and cleaned or polished on both sides at once bypressing the wheels together by the foot.

If the obj ect be of slender form or perforated,

-as a terret-rin g, bridle-bit with its check-rings,

Src. ,the entire surface of it will be acted upon simultaneously,without turning or changing its position, by the penetration of thepolishing agents operating from opposite sides- 'Ihis is especially thecase when the machine is used for scouring, as the brushes employed arepeculiarly adapted to penetrate and embrace all parts of the article,and an operator can thus clean ten times as many pieces, for gold,silver, or nickel plating, as can be cleaned by an expert workman withbrushes by hand.

By revolving the wheels A in opposite directions, the article placedbetween them has hardly any tendency to pull out of the operators hand,and he can therefore handle the pieces more easily and rapidly than uponthe ordinary single wheel. The opposed motions of the wheels serve notonly to force the revolving brushes more thoroughly into the irregularparts of the wor-k, but to catch and retain the polishing-powderdischarged from the faces ofthe opposite wheels.

The wheels may be made'of, any desired shape or material, one of thoseshown in the figure being of plain disk form, with bristles inserted inits face and outer edge, while the other is shown rounded upon the innercorner. 4

The edges of the wheels may be provided with bristles or suitable tuftsof material, to polish certain parts of any article which cannot beproperly cleaned between the two wheels; but such provision upon theedges of the wheels is not essential to the operation of the wheels.

The belt-pulleys on spindles B B will be applied by means of feathersand grooves, or in any suitable manner which will allow endwise movementto be given to the said spindles while they are rotating.

I am aware that scouring and polishing wheels without bristles have beenoperated iu a similar manner; but the arrangements for moving suchwheels toward one another are entirely unsuited for use with abrush-wheel,

upon which the operator requires to use both hands to manipulate thegoods with sucient rapidity; and l therefore claim the devices I haveinvented to operate the wheels by the foot, while the operator uses hishands for the purpose set forth. r

I claim- In a machine for scouring with brush-wheels,

the bent levers t ci, links d d, spring` f, and '1 September, 1879, inthe presence of two wittreedle e, combined with and arranged in thenesses. relation shown to the rot-ary brushes A A and theirendwise-movabie spindles B B, as speei- JOHN A' SPENGE' fied. WitnessesIn testimony that I claim the foregoing I THOS. S. CRANE, have heretoset my hand this 17th daiy of OSCAR WIENER.
